Definitions

  • the present invention relates to a wind aerator for mixing water and in particular stagnant water as described in US-2004/0141851 .
  • the wind aerator will be advantageously intended to equip water bodies prone to eutrophication such as ponds, ponds or lakes.
  • Wind turbines can be divided into two categories, namely those using horizontal axis sensors, including Dutch mills, American mills or fast wind turbines and vertical axis sensors. .
  • the present invention is an improvement to this second type of vertical axis wind aerator.
  • the principle of wind turbines is to use the force of the wind to drive water mixing means allowing the formation of a vertical current allowing the rise of deep water under the surface of the device to the surface and consequently their oxygenation.
  • This rotor is based on the principle of the differential drag, the hemicylindrical shape of the two balls creating a difference in the shape of the airflow and therefore an aerodynamic torque.
  • This type of Savonius rotor is particularly suitable for constituting the wind turbine part of an aerator in particular because it is particularly simple and robust construction and that it also has a large starting torque to start at speeds of weak wind.
  • this type of rotor also has drawbacks and in particular, the fact that this starting torque can decrease and even cancel depending on the orientation of the rotor relative to prevailing winds.
  • the present invention aims to overcome the aforementioned drawbacks and for this purpose to provide a wind generator design of both simple and robust having a high starting torque low wind, especially of the order of a few kilometers / hour and whatever orientation of the latter.
  • Another object of the present invention is to provide a steerable wind aerator according to the resultant wind and to limit the stresses in its structure and more precisely at its floats and / or its aerial part.
  • Another object of the present invention is to provide a wind generator in which the stirring means have a high speed of rotation to obtain a large volume transfer of water around the aerator.
  • said aeolian aerator further comprises at least one additional air sensor disposed on said transmission device and oriented substantially perpendicularly to the main sensor.
  • a wind turbine 1 comprising a platform 2 equipped with at least one float 3, the platform 2 supports a vertical axis air sensor 4 and maintaining water mixing means 5.
  • Said aeolian aerator 1 further comprises a transmission device 6 between the sensor 4 and the stirring means 5.
  • the aerator 1 further comprises at least one additional sensor 7 disposed on the transmission device 6 and oriented substantially perpendicularly to the main sensor 4.
  • the vertical axis air sensor 4 is of the Savonius rotor type.
  • the rotor of the sensor 4 has two blades.
  • the rotor may comprise a greater number of blades and in particular four, to mitigate the torque irregularities inherent in a Savonius rotor with two blades.
  • the additional sensor 7 comprises two vanes 8 interconnected by an amount 9 secured to the transmission device 6, optionally the sensor may comprise a larger number of vanes depending on the desired technical characteristics and in particular the torque.
  • the coupling between the two air sensors 4 and 7 allows the starting and operation of the wind aerator 1 for low speeds and whatever the orientation of the winds with respect to the main sensor 4.
  • the additional sensor 7 also increases the torque developed by the wind aerator.
  • additional sensors chosen from the vertical axis sensors could also be envisaged and in particular the additional sensor could be a Savonius-type rotor.
  • the additional air sensor 7 is oriented substantially perpendicular to the main sensor 4.
  • the angle between the main sensor 4 and additional 7 may be between 80 ° and 90 °.
  • This transmission device 6 comprises a first transmission shaft 10 secured to the two air sensors 4 and 7 coupled to the first shaft 10 and a second transmission shaft 11 on which the water mixing means 5 are positioned.
  • a multiplier 12 is provided making it possible to increase the speed of rotation of the transmission shaft 11 relative to that of the transmission shaft 10.
  • the multiplication ratio is constant between the two transmission shafts 10 and 11.
  • the multiplier comprises manual or automatic adjustment means for modifying the rotational ratio between the transmission shafts 10 and 11. This arrangement makes it possible to control the speed of rotation of the helix of the stirring means 5 and the strength of this stirring.
  • the orientation means 13 comprise at least one directional tail 14 equipped with fins 15.
  • these orientation means 13 are fixed at the level of the structure of the platform 2 and are arranged parallel to the main axis of the floats 3 making it possible to orient the latter in the direction of the waves which corresponds to that of the winds in order to on the one hand, to increase the stability of the aerator 1 and on the other hand, to reduce the stresses due to the impact of the waves on the floats 3.
